CROSS REFERENCE TO RELATED APPLICATIONS

This application relates to Community Plant Variety Office (CPVO) Application/Registration Number 2018/0640, filed in the Europe on Mar. 1, 2018, and the National Service of Certification and Identification of Seeds (SNICS) Application/Registration Number CP-2373, filed in the Mexico on Jun. 28, 2019, both applications of which are herein entirely incorporated by reference for all purposes.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct primocane raspberry variety designated as ‘R15-21-5’.

‘R15-21-5’ was obtained from seed produced by bees pollination of seedlings and was first fruited in Gibraleón (Huelva, Spain) growing fields in 2015. From the seedling and during testing, the plant was designated ‘R15-21-5’. Seed female parent ‘R14-21’ (SD.10.82.6 x ‘Tulameen’) was an unpatented seedling grown in a controlled area with other seedlings and selected for its combination of favorable characteristics on primocane production. The male parent is unknown.

The new variety ‘R15-21-5’ was asexually propagated by root cuttings in a controlled environment at Gibraleón, Huelva, Spain. Asexual propagules from the original source have been tested in Cartaya, Moguer and Palos de la Frontera (Huelva, Spain) growing fields and to a limited extent. The properties of this variety were found to be transmissible by such asexual reproduction. This cultivar is stable and reproduces true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

This invention concerns a new and distinct cultivar of primocane raspberry variety. The varietal denomination of the new variety is ‘R15-21-5’. The new raspberry cultivar ‘R15-21-5’ is distinguished from other cultivars by its combination of traits which include very high production from October to January on primocanes and from April to June on floricanes; semi-upright branched plant; the vigour of the plant is medium-high, the fruit color is light red, trapezoidal-shaped, firm fruit and large size. The cultivar shows a very early cropping season production in protected culture.

DETAILED DESCRIPTION OF THE INVENTION

This invention relates to a new and distinctive primocane raspberry cultivar named ‘R15-21-5’.

‘R15-21-5’ is a semi-upright, medium-high vigorous plant with some branches that produces large fruit size, light red colored and trapezoidal shape.

Fruit production season is much earlier than other cultivars when grown in protected culture, this allows large quantities of fruits in winter and early spring. Fruit is easily removed from its receptacle, with adequate width of the cavity, and easily visible on branches.

‘R15-21-5’ has not been noted to be sensitive to any pest in Huelva (Spain). Specifically, it is relatively tolerant to aphids and spider mites.

Plants of ‘R15-21-5’ are slightly susceptible to powdery mildew (Podosphaera aphanis) when greenhouse grown.

‘R15-21-5’ can be asexually propagated by root suckers, root cuttings and other known methods of propagating raspberry plants. No off-type plants have been observed in the history of asexual propagation of this cultivar by either method.

‘R15-21-5’ is distinguished from seed parent ‘R14-21’ and ‘Tulameen’ by the following characteristics:

Plant. ‘R15-21-5’ shows less vigor than seed parent ‘R14-21’ and a greater number of lateral branches than ‘Tulameen’.

Current season's cane. ‘R15-21-5’ shows less cane diameter than ‘R14-21’ and ‘Tulameen’.

Fruit. ‘R15-21-5’ shows large light red coloured fruit with a trapezoidal shape, and ‘R14-21’ fruit is smaller and the color is darker. Fruit color and shape of fruit is similar to those of ‘Tulameen’ but ‘R15-21-5’ shows larger fruits.

Spines. ‘R15-21-5’ shows less spine density and the spines are smaller than the spines in ‘R14-21’.

‘R15-21-5’ is distinguished from other commercial cultivars by the following characteristics:

General. The onset of flowering on current season's canes in ‘R15-21-5’ begins 100 to 110 days after roots are planted in July. This is earlier than other commercial varieties such as ‘Heritage’ (unpatented variety), which flowers on current season's canes 140 to 150 days after planting in July; or, ‘Adelita’ (U.S. Plant Pat. No. 25,245 P3), which flowers on current season's canes 130 to 140 days after roots are planted in July.

Root. ‘R15-21-5’ shows a denser and thinner root system than ‘Heritage’ or ‘Adelita’.

Plant. ‘R15-21-5’ is more vigorous and shows a greater number of branches than ‘Heritage’ or ‘Adelita’. Branches of ‘R15-21-5’ are thicker than those of ‘Adelita’.

Leaf. ‘R15-21-5’ is distinguished from other commercial cultivars such as ‘Heritage’ or ‘Adelita’ by the shape of the terminal leaflets (FIG. 9). Leaf rugosity in ‘R15-21-5’ is medium, which is more rugosity than that for ‘Heritage’ and less rugosity than that for ‘Adelita’ (FIG. 9). The green color of leaf upper side of ‘R15-21-5’ (RHS, NN137B to NN137C) is lighter than that for ‘Adelita’ (RHS, 138A to 137A) and ‘Heritage’ (RHS, 137A to NN137A) (FIG. 9).

Current season's cane. ‘R15-21-5’ shows glaucosity (Waxy Bloom) presence in canes and branches, meanwhile glaucosity (Waxy Bloom) in ‘Adelita’ is absent (FIG. 10). Cane color in ‘R15-21-5’ is near to RHS, 143B to 144A, whereas in ‘Heritage’ cane color is near to RHS, 142B to 142C.

Spines. ‘R15-21-5’ shows more spine density than ‘Adelita’ and less spine density than ‘Heritage’ in current season's cane (FIG. 10) and pedicel (FIG. 9).

Fruit. ‘R15-21-5’ shows a trapezoidal shaped fruit, meanwhile fruit shape in ‘Adelita’ is conical. In contrast, ‘Heritage’ shows a rounded general shape in fruit. ‘R15-21-5’ shows lighter red colored fruit (RHS, 46B to 46C) than ‘Adelita’ (RHS, 47A to 46A) and ‘Heritage’ (RHS, 59A to 59B).

The results provided below describe production, weight per fruit and Brix degrees of the variety ‘R15-21-5’ and commercial variety ‘Adelita’ (U.S. Plant Pat. No. 25,245 P3) from October 2016 to January 2017 on primocanes (Table 1) and from April 2017 to June 2017 on floricanes (Table 2). The results come from one trial located in Gibraleón (Huelva, Spain). The trial was a randomized complete block design with three repetitions and 6 plants per plot. Root cuttings were cultivated from Jul. 17, 2016 to May 31, 2017. It was cultivated under standard conditions of raspberry cultivation in Huelva, Spain.
